I routinely test with 200,000 channels before making each release although your circumstances are slightly different.
This is bug entry 136 in Mantis.

-----Original Message-----
Hi, I wrote simple cliet that open 10000 channels to the same PV. I remark that I just opened and didn’t do any get/read/subscribe. Then program closes channels and destroys CA. What I saw:
- of course, IOC had one more connections (I used VxStat) - of course, IOC had 10000 more channels - of course, IOC lost some memory. (VxStat shows that the biggest memory pool became less) - IOC CPU loading became 33% (It was ~13-15%).
Last item I couldn’t understand. What IOC (definitely, server layer of IOC) does?
Another problem. I started this program 3 times. After that IOC crashed. Did anybody similar tests?
Thanks, Andrei.
